The search, launched on Monday, comes amid growing concerns over human-shark encounters in the area, where warm waters from a nearby power plant attract dusky and sandbar sharks between October and May.

Shark attacks are rare in Israel, with only two previously recorded, one deadly in the 1940s.
During the Passover holiday, beachgoers shared waters with sharks, some even filmed feeding or grabbing at them.
